Specification of Letters Patent.

Patented May 14, 1907.

Application tiled September 18,1905. Renewed March 15, 1907. Serial No. 362.527.

T0 all whom it may concern.: fBe it known that I, GEORGE GILMORE, a citizen of the United States of America, residing at Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Switches, of rwhich the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in switches.

The invention particularly pertains to a type of construction employed in connection with water filters and discharges therefor, and broadly speaking embodies an electrical switch that is thrown in circuit upon the opening of the faucet, to cause a current to travel through an electrical filter with electrolytical action, thereby freeing the water of extraneous matter.

One of the advantages accruing from the present invention is that no waste of the electrical current is permitted, as heretofore where continuous currents have been employed. Sufficient current may be supplied when the faucet is turned on by virtue of the switch connections with any source of supply either batteries or dynamo, to act instantly upon the water being drawn from the' filter.

The detail construction will appear in the course of the following description, in which reference is had to the drawing forming a part of this application, like numerals of reference designating corresponding p-arts throughout the several views, in ywhich Figure- 1 is a side elevation showing the relative arrangement of the faucet and switch, Fig. 2 is alongitudinal section through the switch, Fig. 3 is a top elevation of the stationary contact member, Fig. 4 is a top elevation of the movable contact member, and Fig. 5 is a top plan view of the switch and base therefor.

As shown in the drawings, the switch is employed in connection with the double circuit electrical stem leading to the storage filter. The construction is so designed that any number of switches and circuits may be employed in connection with a single faucet, in order to operate the various electrical members.

In carrying out my invention I employ a faucet 1 of conventional form, which is provided with an extension 2 of the valve stem projecting through the bottom of the valve casing. The projection 2 is formed with a squared head and is indicated in dotted lines in Fig. land fits into the squared socket 3 formed in an enlarged head 4 of a pintle 5 upon which the movable switch contacts are mounted. The pintle 5 is journaled in a suitable base 6 and isheld thereto by nuts 7. Mounted adjacent to the pintle 5 and disposed in parallel relation thereto, is a bolt 8 provided with an enlarged head 9, and secured in the base 6 by nuts 10. The stationary contact members are mounted upon said bolt 8, being held between the enlarged head 9 thereof and the base 6. The stationary contact members embody plates 11 having the configuration of a key-hole slot and provided at their ends with openings 12 by which they are mounted upon the bolt 8 in concentric relation thereto. The respective contact plates 11 are held from vibratory movement upon the bolt 8 by a longitudinal key 13 which may be of sufficient length to fasten a single plate, or of a suflicient length to fasten a series of plates. The plates 11 are insulated from the bolt 8 by a tube of fibrous packing 14, in which the key 13 interfits. The several plates 11 are arranged in spaced parallel relation, and in the spaces are interposed conductor wires 15 and 1 5a, which severally designate their respective circuits. The wires 15 and 15a are insulated from the plates 11 arranged therebelow by insulating strips 16 of annular form which are concentrically arranged with relation to the tube 14. The lowermost wire 15:L is insulated from the nut 10 and the rest of the structure by a similar annulus. l

The movable contact plates are shown in Fig. 4 and are designated by the numeral 17. These plates are mounted upon the pintle 5 but are insulated therefrom by a tube 1S of similar material and construction tothe tube 14. The plates 17 are rigidly connected to the tube 18 in a similar manner that is by a longitudinal key 19 passing into recesses in said tube and contact plates 17. The contact plates 17 are severally arranged in spaced parallel relation and are electrically connected with one another by wires 20 interposed therebetween. As arranged, there are four pairs of contact plates 17 arranged IOO and adapted when in their proper position to close the respective circuits of the wires 15 and 15a. The plates 17 of each set, as above stated, are electrically connected by the wires 20, but are insulated from the adjacent set by an annulus of any desired insulating material 21. Annular strips of insulating material 22 are arranged between the plates 17 and surrounds the wires 20. The plates 17 are of peculiar construction, being` of the general contour of a semi-disk, being formed with an enlarged portion 23 which forms the contact surface thereof and with a reduced portion 24 which co-acts with the portion 23 in forming awall or a central opening 25 adapted to fit over the insulating annulus 18.

Inloperation, when the faucet is in a closed position, the contact plates 11 will project into the spaces between the plates 17, but will be out of contact therewith, owing to the fact that they will be adjacent to the reduced portion thereof. However, when the faucet is turned sufficiently in any direction to permit of the iiow of water from the storage filter, the plates 17 will come into contact with the several plates 11, thereby closing, through the plates 17 and the wires 2O of each series shown, the respective circuits 15 and 15a, and causing the current to travel through the filter to produce an electrolytical effect therein, or to close an electrical circuit for any lother desired purpose.

It is obvious that various changes may be made without departing from the scope of my invention as defined in the appended claims. Any number of circuits and of corresponding contacts of the switch mechanism may be employed. By loosening the nuts upon the pintle 5 the arrangement of the plates 17 may also be regulated to vary the making and breaking of the circuits with relation to the turning of the faucet dependlng upon the function contemplated.

What I claim and desire to secure by Letters Patent, is z* 1. A switch embodying a supporting plate, a post mounted thereupon, stationary contact members mounted upon said post, insu- .conductors in comnnmication with said con tact members of the several series, insulation interposed between each of said stationery contact members, a pintle rotatably mounted in said base, contact members mounted upon said pintle and insulated therefrom, the contact members being arranged in series corresponding to the series of said stationary contact members, electrical cmiductors interposed between each two contact members of a series, insulation interposed between the adjacent contact members of the several series.

In a switch, the combimttion olt a base,

screwing on the post on each side of the base, a plurality of stationary contact members mounted en said post and insulated therefrom, conductors connected to said contacts, a pintle rotatably mounted in said base, movable contact members disposed in pairs on said pintle, and rotatable therewith, each pair of contact members being electrically connected and each pair of contact' members on the pintle being adapted to embrace one of the contact members on the. post.

In testimony whereof I allix my sigm'tture in the presence of two witnesses:

GEORGE GILMOHE.
